Heat recycling drying machine utilizing inlet/outlet air temperature difference to condense water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drying devices waste thermal and electric energy as hot air is not dehumidified and does not perform heat exchange with external air for recycling, leading to inefficiencies in energy usage.
Innovation Solution
A heat recycling drying machine utilizes an inlet/outlet air temperature difference to condense water, where hot air containing water is cooled through a vertically bent fluid pipeline, allowing condensed water to be collected and reused, and the thermal energy is used to preheat external air, reducing energy loss and saving electric energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If hot air is discharged to the exterior without heat exchange, then the drying process is simple, but thermal energy is wasted
Solution Approach 1:
A pipeline structure with water condensing function is introduced as an intermediary component between the heating space and external environment. This pipeline enables heat exchange between hot discharged air and external air, allowing thermal energy recovery while managing condensation, thus reducing thermal energy loss without requiring a completely complex system redesign
Solution Approach 2:
The system recovers thermal energy from hot air that would otherwise be discarded to the exterior. By routing hot air through the pipeline structure where it exchanges heat with incoming external air, the system captures and reuses thermal energy, reducing overall energy consumption while maintaining operational simplicity
2Loss of substance
If hot air is cooled to condense water, then water can be collected and reused, but the drying process becomes more complex
Solution Approach 1:
The pipeline structure combines multiple functions into a single integrated component: it serves as both the condensation chamber where hot air is cooled and water is collected, and as the preheating heat exchanger for incoming external air. This merging of functions reduces the need for separate complex subsystems while achieving both water recovery and energy efficiency
Solution Approach 2:
The pipeline structure performs multiple functions simultaneously: cooling hot air for condensation, collecting condensed water, and preheating external air for the drying process. This multi-functionality reduces overall system complexity by eliminating the need for separate dedicated components for each function
3Use of energy by moving object
If external air is preheated using hot air thermal energy, then energy efficiency improves, but the system structure becomes more complex
Solution Approach 1:
The system uses its own hot discharged air to preheat the incoming external air, creating a self-service heat recovery mechanism. The hot air from the drying process automatically serves to warm the incoming air supply without requiring external energy input or complex additional heating systems, thereby reducing electric energy consumption while maintaining manageable system complexity

AI summary
Hot air containing water is discharged from a heating space to pass through a vertically bent fluid pipeline (1035) formed by an hot air section (1030) of a water condensing pipeline structure (1029) and a vertically bent flow guiding structure (1032). Meanwhile, external inlet air having relatively low temperature is pumped through an cold air section (1031) of the water condensing pipeline structure (1029) to enable the hot air to be cooled, thereby condensing the water contained in the hot air. The condensed water is collected or flows with a first part of the hot air to pass through an hot air shunt port (1026) for being guided to an external discharging port (109). A second part of the hot air is guided by the hot air shunt port (1026) to flow towards a hot air return inlet (1022), thereby reducing the thermal energy loss and saving electric energy.
